// Notes:
// - This class provides the functionality for a measurement tool.
// - UI frameworks need to provide binding wrappers.
//
// General usage:
// - User clicks on 'Start' or 'End' toggle button.
// - MouseMove over the scene moves a hotspot around.
// - When a mouse click is detected, the Hit point for start/end is updated,
// and the toggle button returns to unchecked.
// - If the check button is unchecked, the Hit point is not set
// - User can still pan/rotate the scene with mouse drag operations
